This module selector adds an adjustable low rpm launch stage to a Three Step Module Selector, letting racers dial in 100 rpm adjustments from the driver's seat as track conditions change. A shielded harness protects against EMI, and the unit also provides a top-end overrev limit and a separate burnout rpm limit for consistent tire temperatures.Specifications: Category: Air and Fuel Delivery Part Type: Engine RPM Limiter Product Type: Module Selector Sub Category: Fuel Injection System and Related Components Adjustable in 100 rpm increments Shielded harness for EMI protection Provides launch, burnout, and top-end overrev rpm limits RPM modules sold separately, not included Part Number: 8735 FAQWhat does the 8735 module selector do?It adds an adjustable low rpm launch stage on top of a Three Step Module Selector, with separate burnout and top-end overrev rpm limits.Are rpm modules included?No, the limits are set with MSD's plug-in modules, which are sold separately.Can the launch rpm be adjusted from the driver's seat?Yes, the adjustable stage can be dialed in from the driver's seat in 100 rpm increments as track conditions change.Why does it use a shielded harness?The shielded harness protects against electromagnetic interference (EMI) so it can be mounted within easy reach of the driver.{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What does the 8735 module selector do?","acceptedAnswer":{"@type":"Answer","text":"It adds an adjustable low rpm launch stage on top of a Three Step Module Selector, with separate burnout and top-end overrev rpm limits."}},{"@type":"Question","name":"Are rpm modules included?","acceptedAnswer":{"@type":"Answer","text":"No, the limits are set with MSD's plug-in modules, which are sold separately."}},{"@type":"Question","name":"Can the launch rpm be adjusted from the driver's seat?","acceptedAnswer":{"@type":"Answer","text":"Yes, the adjustable stage can be dialed in from the driver's seat in 100 rpm increments as track conditions change."}},{"@type":"Question","name":"Why does it use a shielded harness?","acceptedAnswer":{"@type":"Answer","text":"The shielded harness protects against electromagnetic interference (EMI) so it can be mounted within easy reach of the driver."}}]}
